NOTES ON CARBON COPY FOR WINDOWS 
================================

This document contains important information about Carbon
Copy for Windows including the following topics:

  *  Copying files from the Carbon Copy for Windows disks

  *  Information not found in the User Guide
  
  *  Using the SETCOM Utility (using COM3 or COM4)

  *  Files included on the diskettes


COPYING FILES FROM THE CARBON COPY FOR WINDOWS DISKS
====================================================

The files on the Carbon Copy for Windows installation disks are
compressed. The files are not usable until they are expanded.
Setup expands the compressed files as they are copied onto your
hard disk.

If you need to copy files directly from a Carbon Copy for Windows
disk without using Setup, follow these steps:

  1. Copy EXPAND.EXE (located in the \INSTALL directory) from the
     Carbon Copy Setup Disk onto your hard drive. (This utility
     expands compressed files to a useable format.)

  2. Insert the disk with the file you want to expand into drive
     A: (or any floppy-disk drive).

  3. Type the following and press ENTER:

        EXPAND /R x:<filename> y:<filename>

     where x: is the disk drive you are copying from (source)     
           y: is the disk drive you are copying to (destination)

     The compressed file is expanded as it is copied onto your
     hard-disk drive.


INFORMATION NOT FOUND IN THE USER GUIDE
=======================================

Using Carbon Copy with Novell NetWare
-------------------------------------
     The following versions of Novell NetWare components 
     are recommended for proper operation when using the
     Carbon Copy LAN (IPX) driver:

        Windows Components
        ------------------
        NETWARE.DRV:    v2.02 (021026)
        NWIPXSPX.DLL:   v1.32
        NWPOPUP.EXE:    v2.02 (021027)
        VIPX.386:       v1.13 (920903)
        VNETWARE.386:   v1.06 (921015)

        DOS Components
        --------------
        EMSNETX.EXE:    v3.31 (921112) 
        IPXODI.COM:     v2.00 (920904)
        LSL.COM:        v2.00 (920904)
        NETX.EXE:       v3.31 (921112) 
        TBMI2.COM:      v2.10 (911204)
        XMSNETX.EXE:    v3.31 (921112) 

     It is especially important to update to Novell's
     VIPX.386 version 1.13 or later.  The version that
     ships with Windows 3.1 will not work properly.

     These files are available on CompuServe in the Novell
     forum as WINUP7.ZIP and DOSUP6.ZIP.


Using Carbon Copy with 3COM 3C505 LAN Adapter Cards
---------------------------------------------------
     The 3COM 3C505 LAN Adapter card does not work properly
     with Microsoft Windows in enhanced mode.  3COM is working
     on new drivers that will correct this problem.  Contact
     3COM technical support at (800) 876-3266 for more
     information.


Disabling the Host Video on 256-color Cards
-------------------------------------------
     Carbon Copy may not be able to disable the video on
     some 256-color cards.  Changing to a 16-color driver
     will usually correct this.


Display Drivers
---------------
     The Windows display drivers not directly supported by Carbon
     Copy for Windows include the following:

          Olivetti/AT&T monochrome or PVC display
          Quad VGA
          82c441 VGA


Diamond Steath VRAM 1280 16-color Mode
--------------------------------------
     The Diamond Stealth card will not work with Carbon Copy
     in this mode, but it will work with other modes such as
     1024x768 16 or 256-color modes.


XGA 16-color, HP 16-color SVGA
------------------------------
     These cards do not work with Carbon Copy in 16-color
     mode using their native drivers.  However, they will
     work fine using the Windows standard VGA driver.  The
     XGA and HP cards also work correctly with native
     drivers using any of their 256-color modes.


ATI Ultra "Crystal Font" Driver
-------------------------------
     The ATI Ultra "Crystal Font" driver does not work properly
     with Carbon Copy, however, all other ATI Ultra drivers work
     fine, including 1024x768 and 256-color drivers.  If you are
     using this driver, you should use the Windows Setup program
     to select another Ultra driver, and then reinstall Carbon
     Copy.


Using Alt+Tab to Switch Windows during Remote Control
-----------------------------------------------------
     Using Alt+Tab to select a active window from a full-
     screen DOS session in remote control will not display
     the selected banner on the Guest machine.  However,
     the switch still occurs properly, and the new
     application will be displayed as soon as the keys are
     released.


Using Windows 386 Enhanced Mode "Exclusive in Foreground" Option
----------------------------------------------------------------
     Setting this option in a PIF file will interfere with
     Carbon Copy's ability to remote control the application.
     Do not set this option for applications you wish to remote
     control.


Network Warning Messages During Windows Startup
-----------------------------------------------
     Carbon Copy is not able to display Network Warning messages
     during Windows startup.  In order to prevent problems with
     remote control, we recommend disabling these messages using
     the Network option in Windows Control Panel.  If these
     messages are not disabled, you will not be able to view
     the Host screen until the dialog box is removed.  However,
     the keyboard is still active and pressing <Enter> will
     remove the warning message.


"Host is in an unsupported video mode" Message
----------------------------------------------
     Depending on the Host and Guest video hardware, if you
     switch from full screen DOS from the Guest while in Remote
     Control, you may get the message "Host is in an unsupported
     video mode".  This occurs only when Windows is running in
     a Super-VGA mode.  The message will disappear as soon as
     the switch to Windows is complete, and does not indicate a 
     problem.


Using Window's Standard Mode with the LAN (IPX) Driver
------------------------------------------------------
     The TBMI2.COM (TBMI.COM for Windows 3.0a) utility must
     be loaded before Windows can be run in standard mode
     using the network.  If you get a "Communication driver
     is not installed." message, make sure that this utility
     is loaded before you start Windows.

     DOS version 5.0 is recommended on 80286-based machines if
     the LAN (IPX) driver is used for Host operation and DOSHOST
     is loaded.  The CONFIG.SYS file should contain the line:

                DOS=HIGH

     Other versions of DOS may work if you have a utility such
     as QRAM, allowing at least 500K of free memory at the DOS
     prompt after loading DOSHOST.



Increasing Performance on 80286-based PCs
-----------------------------------------
     Most 80286-based machines running at 12-MHz or slower will
     give better performance if the port speed is set at 9600 baud
     or lower.  Using port speeds greater than 9600 baud may
     actually decrease throughput on these machines due to more
     frequent retransmissions.

     If you are running Windows version 3.1, you may use the 
     FasterModeSwitch=1 option in the [standard] section of 
     your Windows SYSTEM.INI file. Enabling this setting causes
     Windows running in standard mode to use a faster method of
     switching from protected to real mode on many 80286-based
     computers. When this setting is enabled, Windows responds 
     quicker to hardware interrupts, screen updates, and improves 
     file transfer speeds. NOTE: This setting has no effect on
     80386-based computers. Some early IBM AT and compatible 
     computers do not support this setting.  Enabling this setting
     on these 80286-based machines may cause them to lock up when 
     starting Windows.


Increasing Performance on 80386sx-based PCs
-------------------------------------------
     For best performance on 80386sx-based machines, we recommend
     running Carbon Copy for Windows in standard mode.

     As with all Windows applications, running Carbon Copy on any
     PC in standard mode will improve performance over enhanced
     mode on the same machine.


Enhancing Mouse Performance
---------------------------
     When using Carbon Copy for Windows with modems that connect
     at 2400 baud, mouse performance can be enhanced by changing
     the QuickMouse parameter in CCW.INI as follows:

          QuickMouse=5

     This change must be made directly using a text editor. 
     (CCW.INI is located in your WINDOWS directory.)  The default
     setting of QuickMouse=2 is best for modems that connect at
     baud rates of 9600 or higher.

     When using modems that have asymmetrical modulation schemes,
     the transmit and receive channels may operate at vastly
     different speeds.  An example of such a modem is the US
     Robotics Courier HST.  For these modems, you may want to set
     QuickMouse as high as 10 for best performance.

     You may also notice better performance by setting QuickMouse
     to a higher value on noisy phone lines.


Disconnecting with the "Exit Windows" Dialog Displayed
------------------------------------------------------
     Because of a limitation within Microsoft Windows, you should
     not disconnect from a Host machine while the "Exit Windows"
     dialog is displayed.  If you do, you may not be able to
     reconnect to the Host system until someone at the host
     machine responds to the dialog box.


Changing the Communications Options
-----------------------------------
     If you change any of the options on the Communications menu
     (i.e. change drivers, WorkStation Name, Port, etc.) while
     DOSHOST is loaded, you should unload and reload the DOSHOST
     program.  Some of the options do not take effect in DOSHOST
     until this is done.
     

Using the Virtual Desktop Feature
---------------------------------
     The Virtual Desktop feature mentioned in the User Guide
     is not available if the Host PC is running Windows 3.0a.
     The Host PC must be running Windows 3.1 to use this
     feature.


Running Setup with Limited Disk Space
-------------------------------------
     Setup requires a minimum of 4Mb of disk space plus 2Mb of
     temporary workspace to install the complete Carbon Copy
     for Windows product.  If your disk space is limited to
     less than this amount, and you have a previously installed
     version of Carbon Copy for Windows on your hard disk, you
     may want to delete it so you have enough space to reinstall
     the product.


Using Carbon Copy along with CPU Intensive Applications
-------------------------------------------------------
     When using Carbon Copy's File Transfer utility along with
     CPU intensive applications (mostly benchmark programs),
     File Transfer may sometimes display the message "General
     Failure".  This means that File Transfer is not receiving
     enough CPU time to do its work.  If this happens, simply
     close the application that is causing the problem and try
     the transfer again.

     If you have trouble connecting to a machine that is running
     this type of program, you may want to try terminating the
     application before attempting a connection.


Changing the Mouse Settings during Remote Control
-------------------------------------------------
     If you change the mouse settings in the Windows Control Panel 
     during a remote control session, the Guest's mouse may 
     temporarily be out of synchronization with the Host mouse.
     If this happens, simply use the keyboard to choose the OK
     button in the Mouse Settings dialog, and the mouse will
     return to normal.

     Note that there is very little reason to change the mouse
     settings on the Host in this way.  Mouse performance is
     mostly affected by the Guest's mouse settings.


HP Intellifont Drivers
----------------------
     The HP Intellifont display driver (IFW.DRV) is incompatible
     with Carbon Copy for Windows.  You should remove this driver
     from your SYSTEM.INI in order to use Carbon Copy.  


Communications Port Not Found Message
-------------------------------------
     If you get a "Communications port not found." message from
     Carbon Copy, you may want to check the "Custom" settings in
     the Port Settings dialog box to make sure they are correct. 
     The settings installed by using the "Default" pushbutton are
     usually correct for most systems.


Using Carbon Copy with Asynchronous Communications Servers (ACS)
================================================================

     See ACS.TXT for application notes regarding the use of
     Carbon Copy with NCSI/NASI and EBIOS/INT14-based ACS
     products.


USING THE SETCOM UTILITY (USING COM3 OR COM4)
=============================================

     In many systems, Windows will not recognize serial ports
     COM3 and COM4.  See SETCOM.TXT for information about the
     SETCOM utility and solutions to this problem.


FILES INCLUDED ON THE DISKETTES
===============================

     See FILELIST.TXT for a list of files included on the
     diskettes.
